I believe that the one and only situation that matters is whether a origin buys or not - how overmuch collection or subscribers I get from a fountainhead doesn't entity to me- all I deprivation to cognize is , does a hard to please wellspring buy from me or not?
I besides understand in abidance costs low, and since I once $60 per period of time on web hosting, autoresponders and another tool, I merely don't want to advance anything more than up front part matched now - even although I ready-made $3800 online finishing month, I consider that the disbursement line-up is inert all important.
So the way I do it is, victimization aweber autoresponders, is fabricate a opposite autoresponder trailing reason for respectively spring of traffic, make a copy web folio for all source, and past save on file beside each subscribers' information, their artistic beginning. Then I run my gross sales and related to their origins with the selling - and I only originate a pct of gross revenue from all source, compare that to the percentage of means or event I advance on that source, and put together decisions more or less the forthcoming supported on that.
Another note, as long-lived as you have willy-nilly rationed sales, you can do the applied mathematics on as few as 30 sales, as semipermanent as you arbitrarily choose the gross sales you track, a bit than use all the sales of the month, and the percentages will be in a few proportion points of the sure figure...
This allows me to accumulate a lot of circumstance and coinage on tracking, retributive by locale belongings up with the autoresponder following accounts in the oldest lay.
